Poor turn around time from VumaTel

Mweb is my ISP and they use VumaTel fiber to connect to my premises, I logged a call with Mweb on Tuesday 19 November 2019 that my internet is off. They did their troubleshooting and dsicovered that the issue was with the VumaTel fiber box. I fault was logged with VumaTel. When i called Mweb today, Saturday 23 November, they told me that the VumaTel technician came to my premises and solved the issue, the report that was given was " too many devices connected". First of all, there was no VumaTel technician that came to my house, second of all, i have only 4 devices connected on my router, 2 cellphones, 1 laptop and a playstation, and since when do connected devices cause a fiber to fail. Third of all, after 5 days of logging the fault, i am still offline. Poor poor services by VumaTel.
